Zap2it asked producer Gale Anne Hurd if we’ll ever see Hershel again, after his death in Episode 8, the mid-season finale. "I'm hoping," Gale said. "We do [flashbacks] rarely, but we have done it from time to time."

They would need to justify the flashback time, but for a major character like Hershel it would make sense. As Gale also said in the same interview, “Hershel really was the one character whose death will resonate the most with everyone. There's no one who didn't like Hershel. He had no enemies. He could be relied upon. Obviously his two daughters are bereft. He had a strong relationship not only with Rick and Carl but also with Glenn.”

Any of them could have flashbacks to Hershel’s wisdom or caution to inform their actions out there in the rest of Season 4, and maybe beyond.
